It’s 1968 in America. Change is blowing in the wind…but seemingly far removed from the unrest in the cities is the small town of Mill Valley where for generations, the shadow of the Bellows family has loomed large. It is in their mansion on the edge of town that Sarah, a young girl with horrible secrets, turned her tortured life into a series of scary stories, written in a book that has transcended time—stories that have a way of becoming all too real for a group of teenagers who discover Sarah’s terrifying home.

Starring Zoe Colletti, Michael Garza, Gabriel Rush, Austin Abrams, Dean Norris, Gil Bellows, Lorraine Toussaint, Austin Zajur and Natalie Ganzhorn, the film is released August 9 in the U.S., followed by August 23 in the UK.
